Product details

Overview

DMP4009SPSWQ-13 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in PowerDI5060-8/SWP (Type UX) package, rated for -79 A at TC = +25°C, with R_DS(ON) of 11 mΩ @ V_GS = -10 V and 19 mΩ @ V_GS = -4.5 V. It is AEC-Q101 qualified, PPAP-capable, and designed for high-current automotive DC-DC converters and power-management functions.

For engineers reviewing the DMP4009SPSWQ-13 datasheet, DMP4009SPSWQ-13 pinout, DMP4009SPSWQ-13 application, or DMP4009SPSWQ-13 equivalent, key selection criteria include its wettable flank for optical inspection, 100% production-tested UIS capability, low R_DS(ON) at -4.5 V gate drive, and IATF 16949-certified manufacturing.

Technical Context

This MOSFET operates as a high-side or synchronous rectifier switch in automotive power systems, featuring a gate threshold voltage (V_GS(TH)) of -1.0 to -2.5 V and robust avalanche energy rating of 394.9 mJ (L = 1 mH). Its thermal resistance R_θJC is 1.05 °C/W, enabling high-power dissipation when mounted on an exposed drain pad.

Dynamic performance includes total gate charge Q_g of 112 nC at V_GS = -10 V and 53 nC at V_GS = -4.5 V, with turn-off delay time t_D(OFF) = 146 ns and reverse recovery charge Q_RR = 22 nC - optimized for fast-switching, high-efficiency buck and boost topologies.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT4009LPSQ-13	R_DS(ON) = 12.5 mΩ @ -10 V; same PowerDI5060-8 package; lower UIS rating (320 mJ)	Suitable for cost-sensitive non-safety-critical modules where 10% higher conduction loss is acceptable	Select if BOM cost reduction is prioritized over peak transient robustness
IPB4009P4L-HM	TO-263-7 package; R_DS(ON) = 9.5 mΩ @ -10 V; higher thermal mass but no wettable flank	Better suited for industrial-grade designs requiring manual rework or legacy board compatibility	Choose only when existing layout uses TO-263 footprint and AOI is not required

Compared with DMT4009LPSQ-13 and IPB4009P4L-HM, the DMP4009SPSWQ-13 uniquely combines AEC-Q101 qualification, wettable flank for automated inspection, and highest UIS rating (394.9 mJ) in the PowerDI5060-8 form factor - making it optimal for safety-critical automotive power stages where reliability and process control are mandatory.

FAQ

What is the maximum safe operating junction temperature for DMP4009SPSWQ-13?

The device is rated for TJ from -55°C to +150°C. Its absolute maximum junction temperature is +150°C, validated under steady-state and transient thermal conditions per AEC-Q101. Derating is required above +125°C ambient when using the RθJA = 32°C/W value on standard FR-4 boards.

Does DMP4009SPSWQ-13 require a gate resistor for automotive PWM applications?

Yes - a 2–10 Ω gate resistor is recommended to dampen ringing and limit peak gate current during 100–500 kHz switching. The datasheet specifies tD(ON) = 11.5 ns and tD(OFF) = 146 ns with RG = 2 Ω, confirming that external gate resistance directly controls switching speed and EMI profile.

Can DMP4009SPSWQ-13 be used in parallel configurations?

Yes - its positive temperature coefficient for RDS(ON) (see Figure 6) enables inherent current sharing. Parallel operation requires matched gate drive routing, symmetrical PCB copper pour, and individual gate resistors to prevent oscillation. Derate total current by 15% for two devices in parallel per Diodes' application guidance.

Is the exposed drain pad electrically isolated from other terminals?

No - the exposed drain pad is internally connected to pins 2–5 and 7–8, forming a single low-inductance, high-current drain node. It must be soldered to a dedicated PCB copper plane serving as both thermal sink and circuit return path; no insulation or solder mask opening is permitted beneath the pad.
